OpaqueToolsBench: Learning Nuances of Tool Behavior Through Interaction

Skyler Hallinan, Thejas Venkatesh, Xiang Ren +4

Tool-calling is essential for Large Language Model (LLM) agents to complete real-world tasks. While most existing benchmarks assume simple, perfectly documented tools, real-world t…

Demystifying Language Model Forgetting with Low-rank Example Associations

Xisen Jin, Xiang Ren

Large language models (LLMs) suffer from forgetting of upstream knowledge when fine-tuned. Despite efforts on mitigating forgetting, few have investigated how forgotten upstream ex…

What Will My Model Forget? Forecasting Forgotten Examples in Language Model Refinement

Xisen Jin, Xiang Ren

Language models deployed in the wild make errors. However, simply updating the model with the corrected error instances causes catastrophic forgetting -- the updated model makes er…
